What are three types of body composition?

People are born with an inherited body type based on skeletal frame and body composition. Most people are unique combinations of the three body types: ectomorph, mesomorph, and endomorph. Ectomorphs are long and lean, with little body fat, and little muscle. They have a hard time gaining weight.A healthy body composition is one that includes a lower percentage of body fat and a higher percentage of non-fat mass, which includes muscle, bones, and organs.
